Rotational Phonons Drive Low-Energy Kinks in Cuprate Superconductors
Yanyong Wang, Manuel Engel, Christopher Lane +9
Angle-resolved photoemission spectroscopy (ARPES) reveals ubiquitous quasiparticle ``kinks'' near 70 meV and 40 meV across cuprate superconductors, often accompanied by…
Ab initio calculations of the thermoelectric figure of merit, within the relaxation time approximation
Laurent Chaput, Henrique Miranda, Atsushi Togo +4
In this paper, we propose a computational framework, based on the VASP and phono3py computer codes, to obtain the thermoelectric figure of merit from the electron-phonon and phonon…
Magnetism-Enhanced Strong Electron-Phonon Coupling in Infinite-Layer Nickelate
Ruiqi Zhang, Yanyong Wang, Manuel Engel +12
Intriguing analogies between the nickelates and the cuprates provide a promising avenue for unraveling the microscopic mechanisms underlying high- superconductivity. While ele…
Exploring the accuracy of the equation-of-motion coupled-cluster band gap of solids
Evgeny Moerman, Henrique Miranda, Alejandro Gallo +7
While the periodic equation-of-motion coupled-cluster (EOM-CC) method promises systematic improvement of electronic band gap calculations in solids, its practical application at th…
Efficient periodic density functional theory calculations of charged molecules and surfaces using Coulomb kernel truncation
Sudarshan Vijay, Martin Schlipf, Henrique Miranda +4
Density functional theory (DFT) calculations of charged molecules and surfaces are critical to applications in electro-catalysis, energy materials and related fields of materials s…
Accurate Electron-phonon Interactions from Advanced Density Functional Theory
Yanyong Wang, Manuel Engel, Christopher Lane +9
Electron-phonon coupling (EPC) is key for understanding many properties of materials such as superconductivity and electric resistivity. Although first principles density-functiona…
